CHAPTER

3 CPU, ROM, RAM

3.1 CPU

The S1C63666 has a 4-bit core CPU S1C63000 built-in as its CPU part.
Refer to the "S1C63000 Core CPU Manual" for the S1C63000.

Note: The SLP instruction cannot be used because the SLEEP operation is not assumed in the S1C63666.

3.2 Code ROM

The built-in code ROM is a mask ROM for loading programs, and has a capacity of 16,384 steps

×

13 bits.

The core CPU can linearly access the program space up to step FFFFH from step 0000H, however, the
program area of the S1C63666 is step 0000H to step 3FFFH. The program start address after initial reset is
assigned to step 0110H. The non-maskable interrupt (NMI) vector and hardware interrupt vectors are
allocated to step 0100H and steps 0102H–010EH, respectively.

3.3 RAM

The RAM is a data memory for storing various kinds of data, and has a capacity of 5,120 words

×

4 bits.

The RAM area is assigned to addresses 0000H to 01FFH on the data memory map. Addresses 0100H to
01FFH are 4-bit/16-bit data accessible areas and in other areas it is only possible to access 4-bit data.
When programming, keep the following points in mind.

(1) Part of the RAM area is used as a stack area for subroutine call and register evacuation, so pay

attention not to overlap the data area and stack area.

(2) The S1C63000 core CPU handles the stack using the stack pointer for 4-bit data (SP2) and the stack

pointer for 16-bit data (SP1).
16-bit data are accessed in stack handling by SP1, therefore, this stack area should be allocated to the
area where 4-bit/16-bit access is possible (0100H to 01FFH). The stack pointers SP1 and SP2 change
cyclically within their respective range: the range of SP1 is 0000H to 03FFH and the range of SP2 is
0000H to 00FFH. Therefore, pay attention to the SP1 value because it may be set to 0200H or more
exceeding the 4-bit/16-bit accessible range in the S1C63666 or it may be set to 00FFH or less. Memory
accesses except for stack operations by SP1 are 4-bit data access.
After initial reset, all the interrupts including NMI are masked until both the stack pointers SP1 and
SP2 are set by software. Further, if either SP1 or SP2 is re-set when both are set already, the interrupts
including NMI are masked again until the other is re-set. Therefore, the settings of SP1 and SP2 must
be done as a pair.
